9A-A=(\(9+1+\frac{1}{3^2}+...+\frac{1}{3^{99}}\))-\(\left(1+\frac{1}{3^2}+\frac{1}{3^4}+...+\frac{1}{3^{100}}\right)\)
8A=\(9-\frac{1}{3^{100}}\)
=>n=100
Cho A= \(1+\frac{1}{^{3^2}}+\frac{1}{3^4}+...+\frac{1}{3^{100}}\)
Biết 8A=\(9-\frac{1}{3^n}\)
Vậy n=???
Cho A=1+\(\frac{1}{3^2}\)+\(\frac{1}{3^4}\)+...+\(\frac{1}{3^{100}}\).Biết 8A=9-\(\frac{1}{3^n}\). Vậy n=...
\(A=1+\frac{1}{3^2}+\frac{1}{3^4}+...+\frac{1}{3^{100}}\).Biết \(8A=9-\frac{1}{3^n}\). Vậy n= ?
\(1+\frac{1}{3^2}+\frac{1}{3^4}+......+\frac{1}{3^{100}}\).Biết 8A=9-\(\frac{1}{3^n}\)
Vậy n=?
\(1+\frac{1}{3^2}+\frac{1}{3^4}+.....+\frac{1}{3^{100}} \)biết\(8A=9-\frac{1}{3^n}\)
Vậy n = bao nhiêu ?
Cho A=1+\(\frac{1}{3^2}\)+\(\frac{1}{3^4}\)+...+\(\frac{1}{3^{100}}\).Biết 8A=9 - \(\frac{1}{3^n}\).Vậy n=
cho A = \(1+\frac{1}{3^2}+\frac{1}{3^4}+...+\frac{1}{3^{100}}\) biết 8A = 9--\(\frac{1}{3^n}\)
A=1\(\frac{1}{^{3^2}}+\frac{1}{3^4}+....+\frac{1}{3^{100}}\) Biết 8A=9-\(\frac{1}{3^n}\)
Cho A=1+\(\frac{1}{3^2}\)+\(\frac{1}{3^4}\)+...+\(\frac{1}{3^{100}}\). Biết 8A=9-\(\frac{1}{3^{10}}\)
